[0045] The transverse portion of the second T-shaped slider 133, which is an integrated structure with the push rod 13, is arranged on the right end of the push rod 13. The second T-shaped slider 133 is used to provide a mounting carrier for the first auxiliary block 143 and other components. The right end surface of the fixed mold 1 is recessed to the left to form a tapered groove 17 arranged narrow on the left and wide on the right. The tapered groove 17 provides a mounting space for the first tapered clamping plate 14 and other components. The vertical portions of the two first T-shaped sliders 16 arranged in a V-shape narrow on the left and wide on the right are respectively arranged on the upper and lower walls inside the tapered groove 17. The first T-shaped slider 16 is used to guide the movement of the first tapered clamping plate 14 and the second tapered clamping plate 15.

[0046] The first conical clamping plate 14, which is arranged to be narrow on the left and wide on the right and extends out of the left side of the conical groove 17, is movably arranged on the upper wall inside the conical groove 17, and the first conical clamping plate 14 is used to provide a mounting carrier for the first auxiliary block 143 and other components, and the second conical clamping plate 15, which is arranged to be narrow on the left and wide on the right and extends out of the left side of the conical groove 17 and is attached to the lower end of the first conical clamping plate 14 and has an L-shaped cross section, is movably installed on the lower wall inside the conical groove 17, and the second conical clamping plate 15 is used to provide a mounting carrier for the second auxiliary block 152 and other components;

[0047] The upper end surface of the first conical clamping plate 14 is concave downward to form a first T-shaped groove 142 which is internally slidably connected to the first T-shaped slider 16 located on the upper side. The first T-shaped groove 142 is used in conjunction with the first T-shaped slider 16 to guide the movement of the first conical clamping plate 14. The lower end surface of the second conical clamping plate 15 is concave upward to form a third T-shaped groove 151 which is internally slidably connected to the first T-shaped slider 16 located on the lower side. The third T-shaped groove 151 is used in conjunction with the first T-shaped slider 16 to guide the movement of the second conical clamping plate 15.

[0048] The lower end surface of the first conical clamping plate 14 is recessed upward to form a plurality of placement grooves 141 extending from the right end of the first conical clamping plate 14. The placement grooves 141 provide a positioning space for the fisheye PIN. A plurality of clamping blocks 154 extending from the upper ends into the placement grooves 141 are equidistantly arranged on the upper end of the transverse portion of the second conical clamping plate 15. The fisheye PIN is clamped by the clamping blocks 154.

[0049] The first auxiliary block 143, which is an integrated structure with the first conical clamping plate 14, is arranged on the left end of the first conical clamping plate 14. The first auxiliary block 143 is used to provide a processing carrier for the second T-slot 147. The front end surface of the first auxiliary block 143 is recessed backward to form a second T-slot 147 that penetrates the first auxiliary block 143 and extends to the left end of the first auxiliary block 143. The second T-slot slider 133 that penetrates the second T-slot 147 is slidably connected to the second T-slot 147. The second T-slot slider 133 and the second T-slot 147 are used in conjunction with each other to flexibly connect the push rod 13 and the first conical clamping plate 14.

[0050] The second auxiliary block 152 which is an integrated structure with the second conical clamping plate 15 is installed on the left end of the second conical clamping plate 15, and the second auxiliary block 152 is used to provide a processing carrier for the fourth T-slot 153. The front end surface of the second auxiliary block 152 is recessed backward to form a fourth T-slot 153 which penetrates the second auxiliary block 152 and extends to the left end of the second auxiliary block 152, and the fourth T-slot 153 penetrates the second auxiliary block 152, and the second T-slot slider 133 which penetrates the fourth T-slot 153 is slidably connected to the fourth T-slot 153, and the second T-slot slider 133 is used in conjunction with the fourth T-slot 153 to enable a movably connected connection between the push rod 13 and the second conical clamping plate 15.

[0051] When in use, the fisheye rods of the multiple fisheye PINs are first inserted into the multiple placement grooves 141 respectively, and then the pusher 12 is used to drive the push rod 13 to move leftward, thereby causing the second T-shaped slide block 133 to move leftward, thereby causing the first auxiliary block 143 and the second auxiliary block 152 to move leftward, thereby causing the first tapered clamping plate 14 and the second tapered clamping plate 15 to move leftward along the tapered groove 17;

[0052] The first T-slot 142 and the third T-slot 151 are respectively moved to the left along the two first T-slide blocks 16, so that the first conical clamping plate 14 and the second conical clamping plate 15 can move inward at the same time during the leftward movement, so that the clamping block 154 is inserted into the placement groove 141 and contacts the fisheye rod of the fisheye PIN, so as to achieve synchronous positioning and clamping of multiple fisheye PINs, effectively reduce the probability of defects such as crushing and displacement of the fisheye PINs during mold closing, improve the product qualification rate, and protect the mold structure formed by the fixed mold 1 and the movable mold 2, effectively ensuring the service life of the mold structure;

[0053] Then, the fixed mold 1 and the movable mold 2 are closed, and molten plastic is injected into the molding cavity formed between the fixed mold 1 and the movable mold 2. The molten plastic in the molding cavity is then cooled, thereby completing the injection molding of the product. After molding, the mold is opened;

[0054] Then, the pusher 12 is used to drive the push rod 13 to move rightward, thereby causing the second T-shaped slider 133, the first auxiliary block 143, the second auxiliary block 152, the first conical clamping plate 14 and the second conical clamping plate 15 to move rightward along the conical groove 17, and with the assistance of the first T-shaped groove 142, the third T-shaped groove 151 and the two first T-shaped sliders 16, the first conical clamping plate 14 and the second conical clamping plate 15 move outward at the same time during the rightward movement, thereby releasing the clamping of the fisheye PIN and realizing the normal material removal operation of the product.

[0055] Embodiment 2: Before using multiple clamping blocks 154 and multiple placement slots 141 to clamp multiple fisheye PINs, the fisheye rods of the multiple fisheye PINs should be placed in the multiple placement slots 141 respectively. In order to ensure convenient placement and removal between the fisheye PIN and the placement slots 141, the size of the placement slots 141 is generally larger than the size of the fisheye PIN. However, most of the fisheye PIN is located outside the placement slots 141, which makes it easy for the fisheye rod of the fisheye PIN to tilt up in the placement slots 141 due to factors such as the fisheye PIN's own weight, resulting in poor stability of the fisheye PIN after placement and affecting the clamping operation of the placed fisheye PIN.

[0056] In order to solve the above problems, Fig.10 and Fig.12 As shown, a plurality of stoppers 144 arranged in a transverse manner and alternately arranged with the placement grooves 141 and fitted on the upper end of the transverse portion of the second conical clamping plate 15 and located at the left end of the vertical portion of the second conical clamping plate 15 are equidistantly arranged on the lower end of the first conical clamping plate 14, and the stoppers 144 are used to limit the clamping positions of the first conical clamping plate 14 and the second conical clamping plate 15;

[0057] A horizontal block 146, which is located at the left end of the limit block 144 and whose lower end is attached to the upper end of the transverse portion of the second conical clamping plate 15 and is located at the left end of the clamping block 154, is installed on the lower end of the first conical clamping plate 14. The horizontal block 146 is used to limit the placement position of the fisheye PIN. A plurality of rectangular grooves 1463 arranged alternately with the limit blocks 144 are formed on the right end surface of the horizontal block 146. The rectangular grooves 1463 provide installation space for the trapezoidal block 1461.

[0058] The trapezoidal block 1461, which is arranged to be wider on the left and narrower on the right and fits on the left end of the clamping block 154, is slidably connected in the rectangular groove 1463. The trapezoidal block 1461 is used to limit the placed fisheye PIN, and the second elastic member 1462 is installed between the left end of the trapezoidal block 1461 and the left wall inside the conical groove 17. The trapezoidal block 1461 is pushed back to its original position through the second elastic member 1462, and the second elastic member 1462 can be a spring.

[0059] Before placing the fisheye PIN, under the action of the second elastic member 1462, the trapezoidal block 1461 will extend out of the rectangular groove 1463, and then the fisheye rod of the fisheye PIN will be inserted into the placement groove 141 and contact the limit block 144, so as to limit the placement position of the fisheye PIN, and make the fisheye rod of the fisheye PIN contact the trapezoidal block 1461, so as to limit the placed fisheye PIN, effectively avoid the occurrence of the phenomenon of the placed fisheye PIN tilting, improve the placement stability of the fisheye PIN, effectively ensure the subsequent clamping effect, and further ensure the qualified rate of the subsequent molded products;

[0060] The push rod 13 is driven to move leftward by the pusher 12, so that the second T-shaped slider 133, the first auxiliary block 143, the second auxiliary block 152, the first tapered clamping plate 14 and the second tapered clamping plate 15 move leftward along the tapered groove 17, and with the assistance of the first T-shaped groove 142, the third T-shaped groove 151 and the two first T-shaped sliders 16, the first tapered clamping plate 14 and the second tapered clamping plate 15 move inward at the same time during the leftward movement, so that the clamping block 154 is inserted into the placement groove 141 and the fisheye PIN is positioned and clamped;

[0061] And during the process of inserting the clamping block 154 into the placement groove 141, the clamping block 154 will first contact the inclined surface of the trapezoidal block 1461, and the clamping block 154 continues to insert, which will cause the trapezoidal block 1461 to move inward along the rectangular groove 1463, thereby pressing the trapezoidal block 1461 into the rectangular groove 1463, ensuring effective clamping of the fisheye PIN.

[0062] Embodiment three: When multiple fisheye PINs are clamped synchronously by using multiple clamping blocks 154 and multiple placement slots 141, the clamping blocks 154 and the placement slots 141 will make extrusion contact with the fisheye rod of the fisheye PIN. When the clamping blocks 154 and the placement slots 141 move outward, adsorption is likely to occur between the fisheye rod of the fisheye PIN and the clamping blocks 154 and the placement slots 141, resulting in a high probability of pulling on the fisheye rod of the fisheye PIN, causing a high probability of deformation of the fisheye PIN, thereby affecting the product qualification rate.

Gas is transported into the plurality of first air holes 145 through the second channels 1451.

Gas is sprayed outward through the first air holes 145.

A plurality of fourth channels 1551 connected to the left end of the fifth channel 1552 are processed inside the second conical clamping plate 15, and gas is supplied to the plurality of second air holes 155 through the fourth channels 1551.

[0065] A first channel 1431 is provided in the first auxiliary block 143, which is located outside the second T-slot 147 and is connected to the third channel 1452 at its right end. Gas is supplied to the third channel 1452 through the first channel 1431. A sixth channel 1553 is processed in the second auxiliary block 152, which is located outside the fourth T-slot 153 and is connected to the fifth channel 1552 at its right end. Gas is supplied to the fifth channel 1552 through the sixth channel 1553.

[0066] The front end surface of the transverse portion of the second T-shaped slider 133 is recessed backward to form a through slot 134 penetrating the second T-shaped slider 133. The through slot 134 provides installation space for components such as the airbag 136. Two airbags 136 are respectively installed on the upper and lower walls inside the through slot 134. Gas is transported outward through the airbags 136. Two auxiliary tubes 131 penetrating the second T-shaped slider 133 and communicating with the airbags 136 are respectively installed on the upper and lower ends of the second T-shaped slider 133.

The two hoses 132 are used together to make the two auxiliary pipes 131 communicate with the first channel 1431 and the sixth channel 1553 respectively;

[0068] Two movable plates 135 which are respectively attached to the upper end of the first auxiliary block 143 and the lower end of the second auxiliary block 152 and are slidably connected to the through slot 134 and extend out of the front and rear sides of the through slot 134 are respectively arranged on the inner ends of the two air bags 136. The air bags 136 can be compressed by the movable plates 135. The first elastic member 137 located in the through slot 134 is installed between the two movable plates 135. The two movable plates 135 are returned to their original positions by the first elastic member 137. The first elastic member 137 can be a spring. The telescopic rod 138 located in the first elastic member 137 is installed between the two movable plates 135. The movement of the movable plates 135 is guided by the telescopic rod 138.

[0069] When the first conical clamping plate 14 and the second conical clamping plate 15 move outward, the clamping block 154 and the placement groove 141 move outward, and the first auxiliary block 143 and the second auxiliary block 152 move outward, and then the two movable plates 135 move outward, so as to stretch the first elastic member 137 and generate elastic force.

[0070] The outward movement of the two movable plates 135 compresses the two air bags 136, thereby transporting the gas in the two air bags 136 to the two auxiliary pipes 131 respectively. When the two hoses 132 are connected, the gas in the two auxiliary pipes 131 is transported to the second channel 1451 and the sixth channel 1553 respectively.

[0071] The gas in the second channel 1451 will be diverted into multiple second channels 1451 when connected with the third channel 1452, and then blown to one end face of the fisheye rod of the fisheye PIN through multiple first air holes 145, while the gas in the sixth channel 1553 will be diverted into multiple fourth channels 1551 when connected with the fifth channel 1552, and then blown to the other end face of the fisheye rod of the fisheye PIN through multiple second air holes 155, so as to inflate the clamping position of the fisheye PIN, cool the fisheye PIN on the one hand, and effectively eliminate the adsorption phenomenon between the fisheye PIN and the clamping block 154 and the placement groove 141 on the other hand, effectively reduce the probability of pulling between the fisheye PIN and the clamping block 154 and the placement groove 141, effectively reduce the probability of deformation of the fisheye PIN, and further ensure the product qualification rate;

[0072] After the fisheye PIN is clamped, the two movable plates 135 will move inward under the elastic force of the first elastic member 137, and the external gas will be transported into the airbag 136 through the auxiliary tube 131, so that the two airbags 136 return to their original state, effectively ensuring the subsequent normal inflation operation.

[0073] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
